EDVARD W. HUNT, OF DENVER, COLORADO.

SPRING BEDfBOTTOIVl.

SPECIFICATION forming part of Letters Patent No. 236,593, dated January11, 1881.

Application filed October 1G, 1880.

To all whom -t may concern Be it known that I, EDWARD WV. HUNT, ofDeliver, in the county of Arapahoe and State ot' Colorado, have inventedcertain new and useful Improvements in @oiled-Wire Spring Bed-Bottoms,of which the following is a speciiication, reference being had to theaccompanying drawings, in which- Figure l is a plan view of my completehedbottom, and Fig. 2 a perspective view of one of the self-adj ustin gopen rings detached.

My improvements relate to that class of coiled-wire spring bed-bottomscomposed of coiled-wire springs permanently attached to a wooden frame;and the object of my improvements is to so construct and secure thesprings that they shall retain their proper relative positions, and asfar as practicable their original resiliency and tension, at all times.

I construct a frame ot' a series of longitudinal slats, A, secured totwo or more transverse slats, B. All of the springs are formed in setsof two, the two springs being coiled from the opposite ends of a singlewire, so that they remain connected together by the middle portion ofthe wire. The springs,in sets of two, which form the outside rows ofsprings laround the margin of the frame, are indicated by the letter G,and the middle portion ofthe wire from which these springs are formedconstitutes the braces D and E for these springs, and is connectedfirmly to the slats A and B, as illustrated in the drawings. Thesprings, in sets of two, which iill up the middle portion of thebed-bottom, are indicated by the letter F, and the middle portion of thewire from which these springs are formed constitutes a loop orloop-ring, G, capable of yielding so as to slightly enlarge or diminishthe size of the loop under strain. After the strain is removed theresiliency of the loop will cause it to resume its normal size andtension. rIhis con- In this manner I form a self- (No model.)

adjusting spring ring capable of being enlarged or diminished understrain, and then of automatically resuming its original diameter andtension.

I represents links, which connect the adjacent springs in the usualmanner, and K represents short links, which connect the springs with theselfadjusting spring-rings, and also connect the springs with theloop-rings G.

By this construction it will be perceived that the exterior springs uponthe frame are all braced to the frame firmly by the inclined braces Dand E, and that these springs are all connected to the interior springsof the bedbottom by the yielding connections formed of the links K andring-loops Gr and rings H.

The result is a very secure fastening of all thel springs in place, andat the same time such automatically adjustable connections between themthat they are not liable to be tilted out of perpendicular under thestrain of a heavy weight upon the bed. Furthermore, the looprings andt-he adjustable rings H serve to ll up the spaces between the tops ofthe springs in a desirable manner for evenly supporting a bed-tick ormattress.

Having thus described my invention, what I claim as new is- 1. rIwocoiled springs formed from the op-V described.
